Specifying Hosts

Use the --hosts option to specify a comma-separated list of host names or IP addresses for the nodes in the database. The hadbm create command creates one node for each host name (or IP address) in the list. The number of nodes must be even. Use duplicate host names to create multiple nodes on the same machine with different port numbers. Make sure that nodes on the same machine are not mirror nodes, and not from different DRUs..

Nodes are numbered starting at zero in the order listed in this option. The first mirrored pair are nodes zero (0) and one (1), the second two (2) and three (3), and so on. Odd numbered nodes are in one DRU, even numbered nodes in the other. With --spares option, spare nodes are those with the highest numbers.
